sash as it swings inwards as well as support-- ing the weight of the slides; and at the same time the sash weights balance the welght of the slides and sash in the ordinary manner when the latter is in its normal vertical position.

A further object of the invention is to provide a window arrangement wherein' locking means are so arranged as to hold the slides against verticle movement when the sash has been swung inwards to a predetermined extent.

With these and otherl objects in view which will become apparent as the s eci. cation proceeds, the invention is more lly described with the aid of the accompanying drawings, in which:

Figure 1 is a front elevation of a window and frame, and

Figure 2 is a section on the line 2 2 of Figure 1.

Figure 3 is a section on the line 3 3 of Fi re 2.

igure 4 is a view showing an angle strip and a sash, the latter swung inwards.

F' `res 5, 6, .and 7 are sections 5 5, 6 6, and 7 respectively of Figure 4.

Fi re 8 is a detail showing a catch for holding the sides of the slides.

Figure 9 shows a sash cord secured on the inner surface of one of the plates on the side of the sash.

Referring now to the drawings, 1 designates a window frame having the usual stops 2. In the stile grooves 2EL between the stops lower and upper slides 3 and 3a are adapted to movel vertically. To these lower and upper slides, and at their lower ends, lower and upper sashes 4 and 4a are pivotally secured by means which will be more particularly described hereinafter. It vwill be noted that the upper slides 3a are wider than the lower slides 3 so as to permit the upper sash 4 to swing inwards between the lower slides. Now, slnoe the construction ofi` the upper and lower sashes, slides, and their co-relating parts lis similar, we will describe in detail the method of construction o f the vlower sasll, slides and other parts connected therewit To the slides 3 angle strips 5 are so secured that one le 6 of each forms a guide for the plates 7 w ich extend the full length of the sash and are fastened one on each side ofthe latter. The plates 7 have their front edges bent over outwardly so that when the sash is in vertical position they will each engage the front edge of one of the legs 6. The other legs 8 of the angle strips extend into the stile grooves 2a contiguous to the rear surfaces of the slides and have Itheir ends 8b bent back on themselves to form a receiving grooveSs for the outwardly projecting portions 9 of the angle-shaped weather strips 10 which are secured to the opposed inner surfaces of thev rear stops 2. The rear surfaces of the bent back portions 8b of the legs 8 then form slides which bear against the face of the rear stops. It will be noted that by this construction the weather strips are utilized also as guides to hold the angle strips and their slides in spaced relation to one another, and so revent the upper' ends of the slides from fallinginwards towards one another when the sash Iis either swung inwards or completely removed. The method of removing the sash will be described hereafter.

Inside the frame 1 are the usual sash weights 12 having ordinary sash cords 13 fastened thereto. The latter pass upward 4around the usual pulleys 14, down between the stops 2, between theslides 3 and the legs 8 of the angle stripsto lower pulleys 15 whlch are rotatably mounted on the inner'surface of the legs 6. Cavities 15 are provided in the sides of the slides to make room for the pulleys 15. The. sash cords pass around these latter pulleys, through the plates 7 and are secured, usually by knots 16, on the inner side of these plates.

On the lower end of each leg 6 a member 17 is fastened; The thickness of these legs and members forms bearing surfaces for pins 18. Intermediately of the length of the latter flats 19 are cut substantiallyl opposite one another, so as to permit this portion of the pins to slide in the slots 20 of the plates 7. In this manner the pins `18 are compelled to turn with the sash and plates. The ends of the pins adjacent to the flats are normally held in posltion in the slots by means of spring catches 21 mounted on the inner sides of theplates 7. The opposite ends of the pins have cam members 22 integral therewith, the ends of these cam f members are adapted to force the inbent ends 23 and 23a of the upset spring sides 24v and 24 of the members 17 outwards.

So that by the rotation of the sash and vits plates 7 the pins and their cam members are turned. When the sash has passed through a predetermined angle the cam members 22 `force the spring sides 24a and 24 out wards. The' former against the inner stops 2, and the latter against the legs 8 which in turn force the legs 9 of the weather strips against the bent over ends 8b and cause the latter to bind against the rear stops 2.

`When thesashes 4 have been swung inwards the spring catches 21 'may be pulled towards one another and the ends of the pins 18 released, so that the latter may be disengaged from the slots 20 and the sash removed from between the slides.

Towards the upper end of the legs 6 of the angle strips 5 catches 25 are pivotally mounted so as to swing downwards and outwards and engage the upper inner edges of the plates 7. -v

When the sash and slides are either-closed ,or open to any desired extent the catches 25 may be moved upwards and the sash released so that it will swing inwards. By pulling the upper part of the sash inwards the latter turns en the pins 18, and the sash cords 13 are pulled outwards as shown in Figure 4, so thatV the weight of the sash is counterbalanced by the sash weights 12, which latter also continue to counterbalance the slides 3 on account of the cords passing around the pulleys 15. This arrangement of the sash cords also eliminates the possibility 'of the sash falling suddenly inwards when the catches 25 are released.

Again the arrangement of the bent front edges of the plates 7 engaging the inneredges of the legs 6 of the angle-strips 5, and the members 9 ofthe weather strips sliding in grooves 8a eliminates any danger of excessive draught due to the builtupconstruction of the sash and guides.
